Update Ignore & Makefile

Fiddled with the Makefile and included the new external function for
just printing individual results as a 'println' style function for
single double values.
Added Custom Binary & Unary Op Support

Chapter 6 of the tutorial completed and custom binary and unary
operators can be added by the user during compile time.
Added a Standard Lib File

Added the start of a standard library by setting up a pile of the
traditionally expected operators for negation, negative numbers, logical
OR and AND.
